JOHN HINES, OF PHILADELPHIA, PENNSYLVANIA.

PROCESS OF MAKING ENAMELED GOODS.

SPECIPICA'IIOII. forming part of Letters Patent No. 322.290, dated July14, 1885.

Application filed May 18, 1885. (No specimens.)

To all whom it may concern:

Be it known that 1, JOHN HINES, a citizen of the United States, and aresident of Philadelphia, Pen nsylvania,have inventeda certain ImprovedProcess of Making Enameled Goods, of which the following is aspecification.

My invention consists of an improvement in the process of makingenameled goods, more particularly plates and similar articles which haveno turned-u p edges to form a rim to hold the enameling-fluid.

Enameled articles have frequently to be passed through the fire severaltimes in order to melt into the enameled surface the lettering,designator decorations desired to make the article complete, and thisrepeated firing burns off the enamel at the extreme edges, so that whenthe article is put into use the metal becomes oxidized and rusted at theedges, with the ultimate result of causing the enamel to peel off, atleast on those portions of the plate or other article near the edge. Toprevent this, I provide for the coating of the edges of the plate orother article with a glaze or flux by dipping the edges, orotherwisc,'previous to passing the article through the fire for the lasttime.

The figure in the accompanying drawing is a View illustrating the mannerof dipping an enameled and partly-fired article into the glaze.

The glaze or flux which I use in carrying out my invention may be of anysuitable or desired color, finely ground in turpentine or otherconvenient vehicle, and into this flux or glaze, contained in a suitablevessel, A, the

. enameled plate B, just before it is introduced into the fire for thelast time, is dipped at the edges, so as to cause the glaze or flux toadhere thereto, and. the dipped plate is then fired. The flux. or glazebeing less refractory than the enamel of the plate or other article, itflows, owing to the heat, until it becomes quite level and forms aperfect surface, thus producing an ornamental border, which at the sametime protects the metallic edges, which would otherwise be bare andliable to oxidize and rust.

I claim as my invention- 1. The herein-described process of makingenameled articles, the said process consisting in applying to the edgesof the articles a flux or glaze after firing and then refiring thearticles so coated, substantially as set forth.

2. As an improvement in the manufacture of enameled articles, the modeherein described of protecting the edges of the article, said modeconsisting in dipping the edges of the same into a flux or glazeprevious to the last firing.

3. As an improvement in the manufacture of enameled articles, the modeherein described of protecting the edges and making an ornamentalborder, said mode consisting in applying to the edges of the articles aflux or glaze ground in a suitable vehicle and then firing the coatedarticles, substantially as specified.

4:. As a new article of mmrufacture, ena1neled goods having their edgescoated with a flux or glaze'in addition to the body of the enamel, asand for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribi'ng witnesses.
